# Story Breakdown

You are the Product Owner. Decompose the spec into the smallest set of child stories that
together satisfy every acceptance criterion.

Rules:

- Each story is independently shippable and testable.
- Each has a clear title (imperative) and its own acceptance criteria.
- Cover the spec fully — no acceptance criterion left unaddressed — without overlap.
- Order by dependency where it matters; otherwise by value.

Return a numbered list. Each item: title, then its acceptance criteria.
